How much charge is required for the following reductions?
(i) 1 mole of `Al^(+3)` to Al
(ii) 1 mole of `MnO_(4)^(-)` to `Mn^(2+)`

Explanation

To solve the question of how much charge is required for the following reductions, we will break it down into two parts:

### (i) Reduction of 1 mole of `Al^(+3)` to Al

1. **Identify the reduction reaction**:
The reduction of aluminum ion can be represented as:
\[
\text{Al}^{3+} + 3e^- \rightarrow \text{Al}
